Examples of ptolemy.data.ScalarToken.subtract()

ptolemy.data.ScalarToken.subtract()
Return a new token whose value is the value of the argument token subtracted from the value of this token. Type conversion also occurs here, so that the operation is performed at the least type necessary to ensure precision. The returned type is the same as the type chosen for the operation, which is the higher of the type of this token and the argument type. Subclasses should implement the protected _subtract() method to perform the correct type-specific operation. @param rightArgument The token to subtract from this token. @return A new token containing the result. @exception IllegalActionException If the argument token andthis token are of incomparable types, or have different units, or the operation does not make sense for the given types.
